HI!
I connected optional incremental encoder ( 2000 cpr) witht Hall 8 pole outs to Fanuc 20F A06B-0352-B731 .
I have tuned hall encoder out signal with motor back emf - it is ok,
I'm trying to control motor by Aerotech BA30-320
Motor spins cw/ccw, but at low rpm no stability, I can stop rotor by hand!
Motor can spin about 2000 rpm
it seems no incremental feedback, only Hall - but incremental encoder connected (Sin, Cos )
I checked the BA-30 settings several times ( have full manual) , changed JP14 position ( encoder to tachometr ) - motor spins without any changes.
Can any help with BA-30 ?
Thank You

I am presently testing some motors on a B30-320 I have used the factory jumper settings,
except JP14 I am using 2-3.

I tried JP14 1-2 and 2-3 - there is no difference
If to disconnect Sin Cos incremental signal - motor spina without changes (slightly increases the speed). I use velocity mode, with all JP by manual.
resolution by manual 1000 -1500 cpr., I use 2000 cpr - is this problem ?

[Al_The_Man]

I do not connect resolver just hall effect commutation.
Al.

[dim371]

"I do not connect resolver just hall effect commutation" - and You have good result ?
Sin Cos feedback signals - is this rectangular pulses are real sinusoidal signal ( like resolver)?
Why can I stop the engine by hand - and the amplifier is not trying to fight ?
Thank You!

[Al_The_Man]

In the manual I have it is section 2.4.2. and fig 2-6 Current Command Configuration.
The one you refer to is the Velocity command config?
I do not have the encoder hooked up, just a battery box. I have it on the bench right now setting up some CUI BLDC encoders.
In the current mode the POTs are set to INPUT CW and Gain fully CCW
See 2.5.1.

[dim371]

I use velocity mode 3.3.1 by my manual - please check is this right?
Attached manual

[Al_The_Man]

I use the next 3-3-2 works fine.
Are you using a battery box?
Al.

[dim371]

What is " battery box?"

[Al_The_Man]

A box using two 9vdc battery's and a pot for simulating the ±10vdc analogue command.
Al.

[dim371]

O, yes two "crone" bat. for +- 10 v
I trying " current control" - motor spins , but I can stop rotor by hand
Where the error - I do not understand

[Al_The_Man]

Sure the drive is OK?
Is it used?
Disconnect power Short the motor phases out and see how hard it is to turn.
Al.

[dim371]

Sorry, I do not understand everything .
I disconnected phases from BA and short any combination - motor spins very hard.

[Al_The_Man]

This is a test of the motor magnet strength, if shorting all 3 and try to spin the motor as fast as possible, the resistance is a measure of whether there is a loss of magnetism.
Al.

[dim371]

OK
Can I check BA servoamp?

[Al_The_Man]

Apart from testing with another motor, I am not sure as the LED's usually indicate a problem?
Al.

[dim371]

No errors by led
Motor spins.
I have bldc vexta 50w motor ( only Hall out) will try this motor
His driver run 24 vdc, BA 110 volt - problem possible ?

[Al_The_Man]

I have run low voltage motor on the BA for test purposes with no problem.
Al.

[dim371]

Vexta motor spins the same as fanuc ( bad start and low rpm, no power on rotor)
